I bought this as a "Vortex v1 voice module", but it is not matching other images I found of (I think) the v1 Vortex. Can anyone confirm or identify this board?
I confirmed with Hyperdyne that this is NOT one of their older Vortex cards. So what is it? A better photo of the writing on the board shows it as "VORTEX 1 REV E". I can find no reference to this on the internet.
